Definitions

  • This disclosure relates generally to airflow control for motor vehicles.
  • the disclosure relates to a vehicle-forward air intake assembly for a vehicle which controls moisture ingestion during vehicle operation.
  • Air intakes are provided for vehicles to allow drawing in fresh air to the vehicle engine and engine bay. This allows provision of fresh air to the vehicle engine for cooling, bringing Rise Over Ambient (ROA) values down. Fresh air intake also allows more fuel to be burned without altering optimum fuel-to-air ratios, etc.
  • ROA Rise Over Ambient
  • the present disclosure relates to a vehicle-forward air intake assembly for a vehicle.
  • the described assembly controls and reduces moisture (snow, ice, etc.) ingestion by the air intake during vehicle operation, improving vehicle driveability and engine performance.
  • an air intake assembly for a vehicle comprising a vehicle-forward air intake inlet, an airflow diverter opening, and a moisture-diverting gutter surrounding a portion of the vehicle-forward air intake inlet.
  • the assembly further includes an air intake inlet shield.
  • the airflow diverter opening may be positioned below the vehicle-forward air intake inlet.
  • the moisture-diverting gutter surrounds at least a top and opposed sides of the vehicle-forward air intake inlet.
  • the air intake inlet shield may define a slope.
  • the air intake inlet shield defines a slope of at least 0.11 (mm/mm) or 11%.
  • the vehicle-forward air intake inlet defines a width dimension of 84.53 mm and a height dimension of 33.53 mm.
  • the airflow diverter opening is positioned 18.87 mm below the vehicle-forward air intake inlet.
  • the moisture-diverting gutter may be a C-channel gutter, in embodiments defining a width dimension of 13.74 mm and a height dimension of 5.04 mm.
  • FIG. 1 shows a vehicle including a front-facing air intake system
  • FIG. 2 shows a vehicle-forward air intake assembly according to the present disclosure
  • FIG. 3 shows an airflow pattern provided by the vehicle-forward air intake assembly of FIG. 2 ;
  • FIG. 4 shows a moisture-diverting gutter and airflow diverting aperture for the vehicle-forward air intake assembly of FIG. 2 .
  • a motor vehicle 100 including an air intake assembly 102 (not visible in this view). This allows provision of fresh air to the vehicle engine (not shown) for cooling, providing air to the engine to allow more fuel to be burned without altering optimum fuel-to-air ratios, etc.
  • conventional front air intake systems also allow intake of moisture from the environment, for example rain, snow, slush, etc.
  • FIG. 2 there is shown a vehicle-forward air intake assembly 200 according to the present disclosure.
  • the air intake assembly 200 is mounted rearward of a vehicle front fascia/upper grille assembly 202 .
  • a vehicle-forward-facing air intake duct 204 is provided, in the depicted embodiment being positioned substantially above a radiator upper seal 206 .
  • the vehicle-forward-facing air intake duct 204 in an embodiment defines an arcuate or L-shaped configuration, and may be housed within a sealed chamber (not shown).
  • An airstream diverter opening 208 is disposed below the vehicle-forward-facing air intake duct 204 .
  • a moisture-diverting gutter 210 is disposed to surround a portion of the mouth 212 of the vehicle-forward facing air intake duct 204 .
  • An air inlet shield 214 is disposed below the mouth 212 of the vehicle-forward-facing air intake duct 204 .
  • air flow (see arrows) is diverted into a tortuous path by the above-described structures.
  • a portion of the airflow is diverted through the airstream diverter opening 208 by the air inlet shield 214 .
  • This reduces air pressure around the vehicle-forward-facing air intake duct 204 .
  • Another portion of the airflow is diverted upwardly, and a recirculation zone is created at top and behind the moisture-diverting gutter 210 .
  • the vehicle-forward-facing air intake duct 204 is shielded from direct air flow.
  • moisture By the portions of the airflow diverted through the airflow diverter opening 208 and the portion of the airflow diverted upwardly, moisture (snow, slush, water droplets, etc.) are diverted from entering the mouth 212 of the vehicle-forward-facing air duct 204 .
  • a third, relatively moisture-free portion of the airflow passes through the mouth 212 of the vehicle-forward-facing air intake duct 204 .
  • the vehicle-forward air intake inlet 204 defines a width dimension of 84.53 mm and a height dimension of 33.53 mm.
  • the air inlet shield 214 in embodiments defines a slope 216 of at least 0.11 (mm/mm) or 11%, i.e. a minimum angle from shielding to inlet of 6.28 degrees.
  • the airstream diverter opening 208 is positioned 18.87 mm below the vehicle-forward-facing air intake inlet 204 and defines an effective size of at least 127 mm width and 26 mm height to provide the desired reduction in air pressure around the air intake inlet mouth 212 .
  • the moisture-diverting gutter 210 is positioned to trap this moisture and divert it from the vehicle-forward-facing air intake duct 204 .
  • the moisture-diverting gutter 210 is disposed substantially along a top and opposed side edges of the mouth 212 of the vehicle-forward-facing air intake duct 204 (see FIG. 4 ).
  • the moisture-diverting gutter 210 is a C-channel gutter having a width dimension of 13.74 mm and a height dimension of 5.04 mm.
  • a forward-facing air intake for a vehicle which minimizes moisture intake during vehicle operation.
  • the described assembly particularly for engines such as high performance or diesel engines having increased suction power, by reducing moisture intake degradation of vehicle drivability is decreased.
  • the air intake inlet 204 By the forward positioning of the air intake inlet 204 , fresh air is drawn into the engine to reduce heat, bringing Rise Over Ambient (ROA) values down.
  • ROA Rise Over Ambient
